IMPROVEMENT IN WAGON-TQNGUE SUPPORTS.

The Schedule referred-t0 in these Letters Patent and making part of the same.

I, J OHN KREHBIEL, M. 1)., of Williamsville, in the county of Erie and State of New York, have inventec a certain new anduseful Improvement in VVagontongue Springs, of which the following is a specification.

Nature of the I mention.

My invention consists in a torsion-spring, combined with the hounds and tongue of a wagon, for holding said tongue up, arranged in the line of the axial bolt of the tongue, as hereinafter described.

Genera-I Description end of the tongue-bolt a, or otherwise connected, and

passing underneath hound A ashort distance, as shown in fig. 2. This holds it in place against turning over.

The main length of the rod sets on top of the hound A and rear end of the tongue, crossing the latter in the line of the axial bolt, when it is bent at right angles, shown at c, and passes through and underneath the tongue a short distance, forming what is; known as a torsion-spring by the twisting power or natural spring of the steelrod itself. The weight of the heavy tongue on this bent end of the rod is resisted by the natural spring of the steel. It takes off from the necks of horses or cattle-the weight of a heavy tongue, and if it be extra heavy two of the torsion-springs may be einployed one attached on each side.

- I'am acquainted with tongue-springs formed of a single piece and coiled around the bolt, one end passing underneath the tongue and'the other under the axle; but these ends are constantly rubbing and wearing against the wood. my invention.

The simplicity of my construction and its cheapness will recommend it to all.

A special advantagewf my spring is its torsion action, by which it does not change its position, but" simply turns in the line of its own axis. In this manner-it is less liable to breakage. It is also less liable to being frozen up by water or snow that gathers on it, or'if it is frozen up it readily clears by turning in an axial line. connecting-bolt so as to produce the minimum amount of rubbing and wearing fracture.

It is apparent that the bolt a might be dispensed with and the spring I) be made to act the double purpose of a bolt and spring by inserting in its place and 1 securing it in such a manner as to produce the elas:

ticity ofthe turning movement. -I do not claim a spring for holding up a wagontongne, in its abstract sense; but

What I claim is. The spring b, attached at one end to the bound A, and extending over the rear end of the tongue as an attachment of the same, and a projection of the spring resting forward under said tongue, the whole arranged as described, and operating in the manner and for the purpose specified.

in witness whereof I have hereunto signed my name in the presence of two subscribing Witnesses.
